Isolation Transformer

We highly reccommend the use of an isolation transformer when testing portable RCD's. The isolation transformer should be plugged in between the power source & the portable RCD. This ensures that in the fixed RCD in the switchboard won't trip in the event of the RCD failing it's test.

• Prevents tripping of fixed RCD's
• Easily Portable
• Robust Design

Very important when testing portable RCD's during business hours to prevent loss of work when an RCD shuts down on a switchboard.
